Dirty Minds: The Neurobiology of Love
Kayt is a member of the American Society of Journalists and Authors (ASJA), the Author's Guild and the National Association of Science Writers (NASW). She has recently returned to the United States after living abroad for six years and has just published her first book, DIRTY MINDS: HOW OUR BRAINS INFLUENCE LOVE, SEX AND RELATIONSHIPS, an exploration of the neurobiology of love (Free Press, 2012).
Kayt Sukel's writing credits include personal essays in the Washington Post, American Baby, the Bark, USAToday, Literary Mama and the Christian Science Monitor as well as articles on a variety of subjects for the Atlantic Monthly, Parenting, Cerebrum, BrainWork and American Baby magazines. She blogs regularly about traveling on the Lowell Thomas Travel Journalism Award winning travel blog, Travel Savvy Mom; and science, love and life at the Houston Chronicle's Hearts and Minds blog.

Kayt Sukel: I think that the revolution in neuroscience is sort of happening in two fronts. One, is the study of epigenetics, and the best way to think of the epigenome is that if the – our genomes, our DNA, is the hardware of a computer, our epigenome is the software. So it’s actually sort of telling our DNA how it should be expressed, how much of a particular protein should be expressed and at what time during our life. And the epigenome is heavily influenced by our environment and not just our environment, our parents’ environment and their parents’ environment. Some of the software programs are so embedded that they make these changes that last for generations, others for just a small period of time.
So, the revolution is really coming in understanding that there is no more nature vs. nurture debate. Nature and nurture are intertwined; they’re really impossible to separate. And as we look at our study of brain and behavior, we need to understand that there is no behavior, there is no biology, outside of the environment.
And then the second point, I think, in neuroscience, for a long time, we’d been gender blind. So many studies, for many reasons, have only focused on males of the species or have not compared men and women, and they haven’t compared male and female brains. And although it’s quite controversial--and for whatever reason, people want to take different to mean smarter or better--I don’t think that we can ignore anymore that male and female brains have certain circuits that are sexually dimorphic the same way that we have downstairs regions that are different. We have some upstairs regions that are different as well. And, moving forward in the study of neuroscience, we’re going to have to really pay attention to the fact that there are these differences, to understand what they mean for behavior.

Here's the science of black holes, from supermassive monsters to ones the size of ping-pong balls.
- There's more than one way to make a black hole, says NASA's Michelle Thaller. They're not always formed from dead stars. For example, there are teeny tiny black holes all around us, the result of high-energy cosmic rays slamming into our atmosphere with enough force to cram matter together so densely that no light can escape.
- CERN is trying to create artificial black holes right now, but don't worry, it's not dangerous. Scientists there are attempting to smash two particles together with such intensity that it creates a black hole that would live for just a millionth of a second.
- Thaller uses a brilliant analogy involving a rubber sheet, a marble, and an elephant to explain why different black holes have varying densities. Watch and learn!
- Bonus fact: If the Earth became a black hole, it would be crushed to the size of a ping-pong ball.
Military recruits are supposed to be assessed to see whether they're fit for service. What happens when they're not?
- During the Vietnam War, Robert McNamara began a program called Project 100,000.
- The program brought over 300,000 men to Vietnam who failed to meet minimum criteria for military service, both physically and mentally.
- Project 100,000 recruits were killed in disproportionate numbers and fared worse after their military service than their civilian peers, making the program one of the biggest—and possibly cruelest—mistakes of the Vietnam War.
In a breakthrough for nuclear fusion research, scientists at China's Experimental Advanced Superconducting Tokamak (EAST) reactor have produced temperatures necessary for nuclear fusion on Earth.
- The EAST reactor was able to heat hydrogen to temperatures exceeding 100 million degrees Celsius.
- Nuclear fusion could someday provide the planet with a virtually limitless supply of clean energy.
- Still, scientists have many other obstacles to pass before fusion technology becomes a viable energy source.
